Just recently we got a questions about a failing REXX/VSE GETMSG function. GETMSG may fail with function code 8 and the message "ARX565I MCSOPMSG FAILED RC=(0012,000)" meaning that the console is suspended. A REXX program can react on a suspended console by deactivating this console and activating it again. I don't go into more detail for now, instead want to point you to the z/VSE Hints and Tips book. There you can find more details on how to resolve that situation, see chapter REXX/VSE, section "Console Command... [More]

Today I have a late blog entry for you. Sorry, that I did not blog the last days. I am investigating a customer issue, and my daughter gave birth to a baby, my first grandchild. Therefore I am a bit busy. I am currently preparing a standalone z/VSE environment in LPAR using install from DVD (z/VSE 5.2) and FTP for data and applications. I only have a TCP/IP connection to that z/VSE system from my Windows PC. Usually my test systems are running in a z/VM guest. From z/VM CMS it's easy to punch a VSE/POWER job into a z/VSE guest....

Today I have two VSE/VSAM tips for you. The first one is related to an VSAM I/O error: VSAM I/O ERROR AFTER RESTORE TO VOLUMES WITH DIFFERENT DEVICE TYPE AND MODEL Customer RESTORED to a VOLUME List of Mixed 3390 Mod 3 and MOD 9 DASD. Trying to BACKUP the Catalog afterwards resulted in IDC31329I DISK I/O ERROR. REPRO resulted in IDC3302I ACTION ERROR IDC3314I ** RECORD OUT OF SEQUENCE: IDC3351I ** VSAM I/O RETURN CODE IS 52 It is not specifically stated in the RESTORE Command, however, RESTORE does a DEFINE of a CLUSTER and is thus...

Today I have a short video for you. It's a good summary of tips, that help our z/VSE Level 2 team to speed up the PMR resolution. The Youtube video is here . Some additional material the z/VSE service team may ask for: Issue the SIR command on the console and make a screen shot from the output or prepare the console log output (EXEC PRINTLOG) The SIR output shows the processor, the z/VM and z/VSE release, VSE Supervisor and VSE/POWER PTF level, number of CPUs, ... Prepare the console log output. We scan that for messages and errors.... [More]

Yesterday there was a post on VSE-L related to DL/I. The question was how to close a DL/I database accessed by CICS, because of a batch job that needed access to the same database. Today's blog entry describes briefly how to close and re-open the DL/I database. Thanks for that summary, Richard. When a DL/I database is open in CICS, it may - depending on VSAM share options and mode of access (R/O, R/W) - need to be closed in CICS before it can be used from a DL/I batch job. The DL/I system calls STOP and STRT can be used... [More]

As mentioned in earlier blog entries CICS TS for z/VSE 2.1 can only run on z/VSE 6.1. During the migration of your CICS environment to z/VSE 6.1, some of your CICS tables need to be recompiled. The migration tasks are described in the CICS TS for z/VSE 2.1 Enhancements Guide. The book is here . If the DFHSPITSP phase or your own SIT DFHSITxx was restored from an old z/VSE system, you will see message DFHPA117 DBDCCICS A 41 VERSION OF MODULE DFHSITSP WAS LOADED. CICS CAN ONLY INITIALIZE WITH THE CURRENT LEVEL SIT. during CICS startup and... [More]
